Formative assessment, also called assessment for learning, focuses on continuously gathering evidence about student learning to inform instruction. Key principles of formative assessment include students understanding learning goals and criteria, involvement in self-assessment, receiving feedback on work quality and how to improve. Effective feedback is directly linked to learning goals, focuses on tasks not students, provides guidance for improvement, and is tailored to individual student needs. Formative assessment requires a shift from teachers judging learning to coaching students through the learning process.
